I'm not sure how much to credit the RG3 vs the NAD, so I couldn't say. Worth a try, though? I know Heyman said he was working on a sublingual version of RG3 + NAD that's non-Rx, so maybe that will be out soon

Thanks for your feedback, Seaweed. I listened to the Heyman interview you mentioned and I took the visual contrast test yesterday and think I did okay? (total score 39/45 (87%); biotoxin score 17/18 (94%))

I see that the visual contrast test is the way to find out if someone is getting better with treatment for biotoxins (source: https://www.survivingmold.com/docs/UNDE ... DITV2A.PDF). Any thoughts on follow-up tests I should consider to be absolutely sure or should I assume I'm good? Nasal culture test mentioned in Bredesen's book? I did have multiple mold experiences in prior homes and used to have many of the classic symptoms (runny nose, eyes, new allergies, stiffness in the am, night sweats, static shocks). But I feel generally fine now.

I have had 2 normal visual contrast tests (VCT), and a pretty obvious case of CIRS based on labs, mold levels in my house, and symptoms. So while I'm not offering an answer to your question, I did want to alert you to the possibility that the VCT might give a false sense of security. From my experience, CIRS is a murky condition indeed.
